EUAA Submission: AEMO Draft 2025 Electricity Network Options Report Consultation
Emily Wood | June 26, 2025
The EUAA made this submission to continue to raise the critical issue of transparency of costs particularly for large energy users to have the most accurate picture of the true cost of the transition.
‘….While we acknowledge AEMO’s revised approach to longer-term cost pressures from building ISP projects that will give a better cost estimate to transmission network augmentation costs, this approach still falls well short of actual reality.
The proposed 2026 ISP cost increases (i.e. after inflation) of 25-55% for overhead transmission line projects and 10-35% transmission substation projects do not translate to existing projects i.e. if we were to take this proposed approach to costings and apply them to the estimates as they appeared in the relevant ISP for the following projects; Project Energy Connect, Marinus Link, HumeLink and Copper String, we still fall well short of the actual latest costs/estimates. We recommend that more work needs to be done on the costing methodology for the ISP to better reflect the actual cost of projects being delivered….’
